Feasibility study of a J/$\psi$ cross section measurement with early CMS data
We report on the methods and plans for measuring the differential $p_T$~ \jpsi$\rightarrow\mu^+\mu^-$ production cross section, using data to be collected in the first LHC run by the CMS detector. Making use of the large B-hadron lifetime, we show how to separate the promptly produced \jpsi's f...
